More vein, less plastic.
Use of arteriovenous fistulas, grafts and central venous catheters for haemodialysis access varies considerably, because of perceived patient variables and preferences of surgeons, nephrologists and dialysis staff. Evidence clearly indicates that the arteriovenous fistula is superior to other methods of access in terms of patient survival, flow rates, patency, infection rates, expense and ease of maintenance. Strategies to increase the use and longevity of fistulas for definitive haemodialysis access include vein preservation, early referral for fistula surgery, preoperative clinical and ultrasound assessment of the venous and arterial systems, access surveillance, good cannulation technique, and aggressive conservatism in surgical and/or radiological correction of fistula problems.
